What are the principal actions of the hormones secreted by the anterior lobe of the pituitary gland?

The anterior lobe of the pituitary gland secretes several hormones, including growth hormone (GH), thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and prolactin. These hormones regulate growth, metabolism, reproductive processes, and lactation.

The anterior pituitary gland, also known as the adenohypophysis, produces hormones that have various principal actions. Growth hormone (GH) stimulates growth and protein synthesis in most tissues. Thyroid-stimulating hormone (TSH) increases the secretion of thyroid hormones and the size of the thyroid gland. Adrenocorticotropic hormone (ACTH) stimulates the adrenal cortex to secrete glucocorticoids like cortisol. Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) regulate reproductive processes, including follicle maturation and ovulation in females, and spermatogenesis and testosterone production in males. Prolactin stimulates milk production in the mammary glands.
